Add config file

[zrajm]

This should be a .ini type config file (just like git's). It will always be read before any buildscript is invoked, and can be used to set up paths, aliases etc. Here's an example (adapted from git(1)):

       #
       # A '#' or ';' character indicates a comment.
       #

       ; Source, script and target directories.
       [core]
           ; Recommended defaults.
           scriptdir = fix
           targetdir = build
           pathadd   = bin

       [alias]
           all   = ./all
           clean = --clean

(Relative paths should be relative to the current working tree.)

Reading of the '.fixrc' config file was added with the '--add-path' option in commit 822acf2.

That option has since been renamed '--exec-path'.
